Builds and develops a technical team, coordinates multidisciplinary programs, supports external collaborations, and translates research objectives into reliable, high-performance experimental platforms.

Leads OQC’s quantum processor design and characterization strategy, setting multi-year research roadmaps and managing multidisciplinary teams across device theory, numerical modeling, hardware co-design, and experimental validation. The role oversees processor development from theory through prototyping, measurement, and validation; aligns architecture with control hardware, software, and product requirements; manages budgets and investments; develops technical leaders; and represents OQC to executives, partners, and the global quantum research community.

Leads OQC’s research software, logical compilation, and systems integration teams in Spain. Sets technical direction, shapes architectures, translates scientific challenges into software capabilities, and guides research tooling from experimentation to production. Builds a high-performing organization, develops technical leaders, partners with research and engineering groups, and integrates quantum computing systems with HPC environments, third-party platforms, and community tools.

Develop and maintain compiler and runtime software for quantum computers using Python, C++, LLVM, and related toolchains. Responsibilities include designing and implementing features, bringing algorithms into production, debugging complex issues, maintaining legacy code, testing, code review, and evaluating technical trade-offs. The role involves full software development lifecycle ownership, collaboration with research and engineering teams, technical communication, and mentoring.

Drive OQC’s highest-priority strategic initiatives and C-suite-sponsored programs from strategy through execution. Build integrated delivery plans, coordinate cross-functional workstreams, manage dependencies, track milestones, surface risks, and keep executives informed. The role suits a strategy consultant transitioning into industry, with responsibility for delivering business-critical outcomes and influencing senior stakeholders without direct authority.

Own HR operations across systems, employee data, payroll coordination, policies, governance, and the employee lifecycle. Administer Workable, ClickUp, CharlieHR, and HiBob; maintain audit-ready records and controls; coordinate onboarding, offboarding, benefits, and payroll; improve workflows through automation and AI-enabled solutions; manage vendors and operational projects; and support junior People Operations colleagues across a hybrid, multinational environment.

Lead OQC’s Technical Services function, managing technicians, machinists, and supervisors while overseeing UK technical spaces, including cryogenic laboratories, assembly workshops, and machining facilities. Responsibilities include operational safety and reliability, maintenance, supplier relationships, budgets, reporting, cross-functional projects, continuous improvement, and delivery of Engineering Operations priorities. The role requires strong people leadership, project ownership, stakeholder management, forecasting, and operational discipline in a complex engineering or scientific environment.

Responsibilities include team leadership, technical-space operations, maintenance, supplier and contract management, budgets, operational reporting, project delivery, continuous improvement, and Engineering Operations roadmap execution. The role requires strong stakeholder management, forecasting, operational discipline, and experience in complex manufacturing, engineering, or scientific environments.

Own mechanical design packages for high-precision quantum computing components and assemblies, from requirements and concept development through CAD, structural and thermal analysis, production drawings, and manufacturing release. Collaborate with specialists, suppliers, and manufacturers to resolve integration, tolerance, and manufacturability issues. Support laboratory, workshop, fit-check, verification, and initial build activities across room-temperature and cryogenic environments.

Own engineering configuration data, Bills of Materials, hardware release records, and revision traceability. Administer Arena PLM and SolidWorks PDM workflows, facilitate engineering change processes, review technical release packages, and resolve discrepancies across CAD, PLM, PDM, and downstream systems. Improve configuration-management and release workflows while collaborating with engineering, operations, supply chain, laboratory, and workshop teams to ensure physical builds align with released hardware information.

Develop, characterise and demonstrate hardware components and subroutines for quantum error correction. Design and run experiments, bring up prototype QPU devices, develop experimental-control software and data-analysis workflows, and build system-level understanding of control electronics, cryogenics and signal delivery. Own R&D projects end-to-end, report findings, and mentor junior engineers.

Coordinate end-to-end deployments of quantum computing systems into commercial data centres, managing planning, installation, commissioning, validation, and go-live. Maintain project plans and documentation, liaise with engineering, manufacturing, supply chain, vendors and customers, monitor progress, budgets and risks, and travel to support installations and maintenance.

Leads complex technical and scientific projects from definition through delivery, establishing strategies, milestones, governance, budgets, and resource plans. Manages risks, issues, dependencies, and competing priorities while influencing technical teams, senior stakeholders, and sponsors. The role requires independent decision-making, evidence-based recommendations, and strong communication across technical and business functions. It also drives continuous improvement in project management practices, tools, and governance.

Provide 1st and 2nd line IT support across Windows, macOS, Linux, cloud platforms, networks, applications, and hardware. Own tickets through resolution, support incident and problem management, monitor systems, manage assets and user onboarding/offboarding, maintain documentation, and contribute to automation, security, compliance, audits, backups, recovery, and cross-functional IT projects. Escalate complex issues while collaborating with 3rd line specialists and supporting a growing quantum computing organization.

Support global deployment, commissioning and operation of quantum computing systems in commercial data centres. Develop SOPs, documentation and training, provide remote and on-site technical support, drive preventive and corrective maintenance, capture lessons learned, and collaborate with engineering and data centre partners to improve reliability, serviceability and compliance.

Monitor live quantum cryogenic systems, triage alerts, provide first-line incident response, develop dashboards and alerting strategies, analyse incidents for root causes, collaborate to improve observability tooling, document processes, and automate operational responses to maximise uptime and reliability.

Develop and validate quantum control methods to improve gate fidelity and stability. Design and optimise pulse shapes, characterise gate error mechanisms, build experimental pipelines and benchmarks, define calibration requirements, evaluate devices, and transfer techniques into production software and operational workflows.

As a Senior RF Engineer at OQC, you'll design RF systems for quantum computing, lead development, and collaborate with multidisciplinary teams to optimize performance.

Lead and grow a multidisciplinary Quantum Error Correction research organisation, set QEC strategy, develop error correction and mitigation techniques, coordinate hardware–software co-design, manage budgets and partnerships, mentor technical leaders, and represent OQC at conferences and with customers to drive fault-tolerant superconducting quantum hardware.

As a Senior FPGA Engineer, you'll design and deliver precision control hardware for quantum computing, resolving complex technical challenges across FPGA architecture and real-time signal processing, while mentoring junior engineers.
